| Abstract: | We have determined the specificity of sera elicited by glutaraldehyde-stabilized bovine aortic actin. This modification induces a high titre of antibodies directed against the N-terminal (residues 1-39) and the C-terminal region of smooth-muscle actins. The crude antisera were purified on peptide (corresponding to the 1-9 or 1-8 N-terminal sequences of smooth-muscle isoactins)-polyacrylic-resin columns. By fractionating the antisera we obtained oligoclonal antibody populations specific for each isoactin. |
